The user can adjust the parameters and rerun the simulation and analysis many times in an efficient manner until the optimum operating conditions of the desired system are reached. The user can then archive the system design and implement the system with a greater level of confidence in the ability of the design to meet the requirements of the application.

TECHNICAL FIELD

The subject invention relates generally to industrial control systems, and more particularly to motion simulation systems that interact with industrial control system databases based in part on selecting and analyzing motion components and behaviors.

BACKGROUND

Motion controllers are special-purpose computers utilized for controlling motors, drives, and other aspects of a mechatronic system. Designing a system where drive technology is utilized is difficult because of the complexities and unknowns involved in a motion system. For instance, what system load to motor inertia ratio is acceptable, how will compliance and/or backlash between the load and the motor impact performance and what performance can be expected. The difficulty in answering these and many other questions are related to the complex relationship between load, mechanism, servo motor, feedback, servo drive, controller and gain settings.

Typically, determining answers to these questions involved building a prototype machine and conducting empirical tests to collect data and determine the proper combinations of machinery and configuration parameters. Another possibility for a few designs included the use of general simulation software if the intended design fit within the constraints of the simulation software. Even for those designs meeting the narrow constraints of the general simulation software, the task was difficult because of the requirement of large amounts of design information that was unknown at design time.

The large expense and specific requirements of this type of system has created market pressure for a system that can simulate a servo driven mechatronic system for allowing the selection of components to build the system without the necessity of prototyping the machinery or knowing many of the system dynamics details. In another aspect, market pressure requires ease of use of the simulation system with regard to knowledge of servo driven systems. There is a need in the market for a system that is aware of currently available hardware and configurations and does not require the user of the system to provide all the intelligence of what hardware to select and what parameters to configure and their values.

Referring initially to FIG. 1, a servo driven mechatronic visualization system 100 for analyzing the selected components and simulating the operation of the servo driven mechatronic system is depicted. The system provides a mechanism to design and test a servo driven mechatronic system without the costly expense of prototyping the system or the lengthy lead time to configure a generalized simulation software package to investigate whether the selected components are operationally acceptable and compatible.

It is contemplated that the servo driven mechatronic visualization system 100 can form at least part of a system development visualization system, but is not limited thereto. For example, the servo driven mechatronic visualization system 100 can be employed to facilitate creating a servo driven mechatronic system related to automation control systems, devices, and/or associated equipment (collectively referred to herein as an automation device(s)) forming part of a production environment. Servo driven mechatronic system 100 includes interface component 102, visualization component 104, storage component 106, database access component 108, analysis component 110 and simulation component 112.

The interface component 102 is communicatively connected to Input/Output devices. The interface component 102 provides for object or information selection, input can correspond to entry or modification of data. Such input can affect the configuration, graphic display, reports and/or automation devices. For instance, a user can select a motion application from the list of previously created applications or he can instruct the servo driven mechatronic visualization system 100 to create a new application. Additionally or alternatively, a user could modify axis parameters such as load type or actuator type. By way of example and not limitation, the user could select a transmission by selecting the transmission type, and entering the ratio of transfer, the effective inertia, the efficiency with regards to torque-dependent losses and the friction torque. It should be noted that input need not come solely from a user, it can also be provided by an automatic model computation based on information in a database related to the selected transmission type.

The interface component 102 receives input concerning displayed objects and information. Interface component 102 can receive input from a user, where user input can correspond to object identification, selection and/or interaction therewith. Various identification mechanisms can be employed. For example, user input can be based on positioning and/or clicking of a mouse, stylus, or trackball, and/or depression of keys on a keyboard or keypad with respect to displayed information. Furthermore, the display device may be by a touch screen device such that identification can be made based on touching a graphical object. Other input devices are also contemplated including but not limited to gesture detection mechanisms (e.g., pointing, gazing . . . ) and voice recognition.

One or more of the configuration displays contain data entry fields, buttons, check boxes or dropdown menus for selecting components and their associated configuration parameters. For example, the display graphic can have a section labeled “Voltage Selection” for the operator to configure the supply type, the voltage type and the nominal voltage. In another example, the user can configure the load data by entering the mass, the external force and the coefficient of friction related to the load and table mass. Additionally, the user can select an inclination depicting the path of travel of the load.

The storage component 106 provides the ability to archive preconfigured process motion application solutions, preconfigured servo driven mechatronic visualization systems including displays, reports and graphs and user configured components of the visualization system 100. Additionally, any databases created by the user are archived on the storage component and can be communicated to server data stores 1230 or other servo driven mechatronic visualization system clients 1310.

In another aspect, servo driven mechatronic application data is maintained on the storage component 106 for future review with regards to creating new preconfigured servo driven mechatronic systems 100 or updating existing servo driven mechatronic systems 100. The storage component 106 can automatically transfer its database of preconfigured servo driven mechatronic systems 100 to other server data stores based on a timed schedule an event such as the selection of similar components at another servo driven mechatronic system. For example, if a user configures a parameter associated with a particular transmission type and archives the application model to the storage database 106, the servo driven mechatronic system 100 can automatically update all other servo driven mechatronic systems containing the preconfigured transmission as a default selection. In this manner, the efficiency of the overall servo driven mechatronic system design is improved because better default choices are available. If the particular transmission is selected at another location then the user at that location can select the preconfigured transmission parameters without the time consuming and costly step of analyzing the components.

The database access component 108 provides methods and functionality allowing the user access preconfigured motion component databases and user configured motion component databases. In one aspect, the preconfigured motion databases allow the user to select standard commercially available components for use in an analysis and simulation. In another aspect of the subject innovation, the user can create databases containing custom designed components for use in selecting components for the analysis and simulation. In another aspect, the database access component allows the user to select preconfigured or user configured databases from other servo driven mechatronic systems communicatively connected with the user's system.

The analysis component 110 provides the user the ability to analyze the data generated by the simulation.

For example, this information includes motor parameters such as but not limited to inertia ratio, peak torque and temperature rise. In another example, the information includes drive parameters such as but not limited to average amperes, peak amperes and bus volts.

In another aspect, the user can make changes to the parameters associated with the selected components and perform another analysis based on the changes in the configuration. This method results in the generation of different solutions for the design of the intended servo driven mechatronic system. After generating the different solutions the user can review the analysis of each solution and select the best solution and therefore the best components for the intended application.

The simulation component 112 provides the user the ability to simulate the running of the servo driven mechatronic system based on the selected components and configuration parameters. In another aspect, the simulation component 112 interacts with a database from a motion controller providing the user the ability to tune the selected components and their associated parameters to optimal conditions based on the information provided by the databases.

In one aspect, user input component 202 provides the capability for a user to input manual data to select and configure a servo driven mechatronic system. The user can add this information manually with the input devices such as but not limited to a keyboard and mouse. For example, the user can add an actuator type mechanism component to the servo driven mechatronic system including the initial specification of parameters such as actuator type, pinion pitch circle diameter, pinion inertia, losses and table mass. At a later time, when simulations have provided initial information, the user, using the user input component 202, can add additional information or comments to the servo driven mechatronic system to further tune the servo driven mechatronic system or extend the solution to other aspects or machines of the process. The enhanced solution can then be communicated to other servers or servo driven mechatronic systems to decrease overall design time by providing greater insight into the servo driven mechatronic system.

In another aspect, the automated input component 204 provides the user the ability to automatically import motion application data. For example, the user can instruct the servo driven mechatronic system to import axis data. The user can choose to import the selected axis data into the currently displayed motion application or into another motion application defined on the servo driven mechatronic system. In another aspect of the subject innovation, if the selected motion application has more than one axis defined, the user can select the particular axis for application of the imported data.

It should be noted that the user can manually transfer the motion applications to or from another servo driven mechatronic system or server or the servo driven mechatronic system can automatically transfer the motion applications to other servo driven mechatronic systems or servers based on events such as but not limited to a user changing some aspect of a motion application.

In another aspect, the configuration component 304 provides for exporting motion applications to different formats for use by other software applications. For example, the motion application can be exported to a delimited text file of the user's configuration or to a document in a word processor format. It should be noted that the described formats are exemplary and other formats are possible based on the user's indication.

Configuration component 304 can also allow the configuration of a motion application based on predefined templates. The predefined templates can be categorized as standard templates such as but not limited to press roll feed and cutter knife drive or as advanced templates such as but not limited to crank and four-bar linkage. These templates provide a starting point for creating motion applications associated with typical motion operations. The templates can then be customized by the user to meet the user's specific motion application. Upon completion, the user can create new templates based on the final configuration thus creating a more accurate starting point for future simulation applications.

This analysis directs the user to the appropriate segment for consideration of design changes that will have the greatest impact on servo driven mechatronic system efficiency of operation. If the user chooses, the other segments can be reviewed and are presented to the user in order of descending peak torque.

In another aspect, the compliance/backlash component 112 can automatically include backlash data for the gearbox from the database in place of or in addition to the manual data provided by the user. The inclusion of compliance and backlash data allows the compliance/backlash component 602 in concert with the simulation component 112 to calculate any predicted resonance characteristics of the mechatronic system. In many applications these constraints will provide the limits of performance of the mechatronic system.

The network component 604, in another aspect of the subject innovation, provides the user with a mechanism for manually entering network parameters associated with simulating the operation of the mechatronic system. For example, the user can enter the network update allowing the network component 604 to predict the behavior of the mechatronic system between data samples. The user can adjust the entered update rate value in the simulator and run additional simulations to determine if another network update rate would lead to a mechatronic system with greater stability for the selected components.

In another aspect of the subject innovation, in combination with the user's manually entered data, the network component 604 can automatically select network model parameters from the mechatronic system database. The data provided from the database allows the network component 604 to fine tune the simulation to make a better estimate of the characteristics of the mechatronic system because of the ability to determine the impact of the identified network and its associated parameters on the operation of the components of the mechatronic system. For example, the network component 112 can allow for the lag time between the occurrence of a specific event at one of the mechatronic system components and the notification to the controller of the event. Accordingly, the simulation component 112 prediction of the behavior of the mechatronic system more accurately represents the system based on the selected components.

In another aspect of the subject innovation, the controller component 606 provides the user the ability to simulate the process control loops embedded in the mechatronic system controller.

In another aspect of the subject innovation, the controller component 606 simulates a cascaded control loop structure as illustrated in FIG. 14. A position proportional integral control loop is cascaded into a velocity proportional integral control loop that is cascaded in a current control loop. The initial loop parameters are entered either from the user's manual entry, from an automatic search of the database or from a combination of manual user data and automatic data base search. After each simulation the user can manually change the data entries for each control parameter. In another aspect of the subject innovation, the user can select an automatic control loop tuning function providing the user the ability to allow the simulation component 112 to provide loop parameters based on simulation data. The user can choose to tune an individual parameter or select a plurality of parameters for automatic tuning.

The controller component 606, in another aspect of the subject innovation, can automatically tune different components of the control loops based on the application type. For example, the user can select an application type from basic, constant speed, point to point and tracking. After selecting the application type, the user can select one or more control loop parameters to include in the automatic tuning calculation. For example, the user can select one or more of the parameters of position integral, velocity integral, velocity feedforward, acceleration feedforward, torque offset and output filter. After selecting the desired parameters, the user initiates the automatic control loop tuning calculations and the best parameters are calculated, entered into the data fields and presented to the user. The user can then run a simulation with the calculated parameters and evaluate the performance of the automatically tuned control loop parameters.

Referring now to FIG. 7, the storage component 106 includes a model storage component 702 and a system storage component 704. Storage component 106 can be any suitable data storage device (e.g., random access memory, read only memory, hard disk, flash memory, optical memory), relational database, XML, media, system, or combination thereof. The storage component 106 can store information, programs, historical process data and the like in connection with the servo driven mechatronic system 100. In one aspect, the model storage component provides the capability to store a plurality of preconfigured motion application models. The preconfigured motion application models can be organized by any criteria and made available for selection by the user. For example, the user can choose a preconfigured motion application model based on the production line type or on a particular machine operating as part of the production line.

At the users' discretion, new motion application models can be created and stored based on changes to the production line or a particular machine. The operator can also combine multiple motion application models to create a new larger motion application model. For example, the operator can select a press roll feed, template and add a cutter knife drive template. The operator can then modify the default configurations of the templates to match the operator's motion application requirements. The model storage component 702 also allows the preconfigured motion application models to be shared with server data stores 1230 or other servo driven mechatronic systems 100 through any of the communicatively connected systems.

In another aspect, the system storage component 704 provides storage for all the components required to operate the servo driven mechatronic system 100 and the simulation and analysis data collected based on operator invocation of the simulation. As with the preconfigured process problem solution models, the collected simulation and analysis data can be shared among server data stores 1230 or other servo driven mechatronic systems 100. A maintenance system associated with the system storage component 704 provides for automatically backing up changed preconfigured motion application models and simulation and analysis data based on a timed frequency and an indication that the system storage component 604 is reaching full capacity.
